Stockholm, SwedenEricsson Power Modules has developed a full-brick DC/DC converter that offers high levels of efficiency and is a drop-in replacement for new and old 24 V input designs.
Ericsson Power Modules' advanced DC/DC converter platform designated the PKY2616PI is aimed at RF power amplifier applications.
According to Ericsson, the PKY2616PI delivers 600W output power and typically exceeds 94 percent efficiency. The device's efficiency curve is virtually flat from 30 percent to 100 percent load. Ericsson attributes this level of performance to a specially optimized topology and advanced rectification techniques (patent pending).
The device is designed for 24V DC system voltages and has an input voltage range of 18 to 36-V. For safety and availability, it can withstand up to 50V input continuously. The output voltage is factory set at 28V and the device features an ultra-wide output voltage trimming range that can be adjusted from 32V down to 10V, making the PKY2616PI useful for different RF power amplifier technologies and applications, as well as other applications that require a regulated voltage, such as cooling fan trays in forced convection cooled equipment.
The PKY2616PI has a typical 20mV load and line regulation with ±1 percent set voltage over a base-plate temperature range of -40°C to 100°C.
The device delivers full power at 100°C base plate temperature, and uses only high-reliability ceramic capacitors. Fully current-limit protected, the device has overvoltage protection on input and output connections. The PKY4716PI fully complies with RoHS requirements.
In OEM quantities the PKY2616PI is priced at $77.
